The CUI Inc. SMI24-24-K-P5R is a versatile 24W AC-DC power supply belonging to the SMI24 series. It features a compact wall mount form factor (Class II) suitable for international use, accepting a universal input voltage range of 90 to 264 Vac and a frequency range of 47 to 63 Hz.
This power supply delivers a stable 24Vdc output with a maximum current of 1A, providing up to 24W of continuous power. It meets DoE Level VI and CoC Tier 2 efficiency standards, ensuring energy efficiency with a typical no-load power consumption of less than 0.075W. Key electrical specifications include a maximum ripple and noise of 240mVp-p and an average efficiency of 88.8%.
Designed for safety and reliability, the SMI24-24-K-P5R includes over-voltage, over-current, and short-circuit protections. It is certified to UL/cUL, RCM, CCC, and PSE safety approvals and certified to 60950-1 and 62368-1 standards. The unit operates within a temperature range of 0°C to 40°C and features a 3000 Vac isolation voltage.
The output is delivered via a standard barrel plug connector (2.1mm I.D. x 5.5mm O.D. x 9.5mm) with positive center polarization. The input utilizes a multi-blade connector, sold separately, allowing for interchangeable AC blades for global use. The cord length is 1.50 meters.
